Hello. Take a look to this: www.geocities.com/k_pullo/potentia.htm Basically, it's a method to trigger an enormous energy transfer, using a little energy input. A difference on potential energy between two points allows opposite forces (making a virtual zero) to create a real transference. Changing the little potential levels, these transferences happens once and again, converting potential energy of an elastic mechanism into potential energy of water weight, then into kinetic energy of water transfer, then into potential energy of the same water weight than before, and finally into potential energy into another elastic mechanism. This transfer is modulated by the little potential difference created on water levels without changing the water weight. Tell me what do you think.
